Penny: Wow, that's all you got after you were the most obnoxious person on a double date that included Howard Wolowitz?

Howard: Let me show you another way to look at this. Here we have the universe of all women. These are the ones you want to sleep with. These are the women who believe exactly what you believe. These are the women who would be willing to sleep with you. And right there in the little triple intersection is your ideal mate. Odds are she's a short physicist with low self-esteem who lives in a government research facility in China.

Howard: I don't like to kiss and tell, but somebody made it to eighth base.
Leonard: What the hell is eighth base?
Howard: Seventh base with shirt off. Well, my shirt.

Raj: They get girlfriends and they just abandon us?
Sheldon: It is great, isn't it? We have a wonderful evening ahead of us.

Raj: Come on, Sheldon, the world is filled with people doing things outside. Let's go outside. Outside is good.
Sheldon: If outside is so good, why has mankind spent thousands of years trying to perfect inside?

Sheldon: I would like a root beer float.
Raj: Sheldon, they don't have ice cream.
Sheldon: They don't? Well, apparently these people and I differ greatly on the definition of party.

Raj: He'll have a Shirley Temple.
Sheldon: And don't be chintzy with the Shirley.

Leonard: I'm sorry, but facts are facts.
Penny: Right, and if you can't understand it, it's not a fact.
Leonard: No, if it's not a fact, it's not a fact.

Stuart: I will give you the address if you go to my cousin's wedding with me.
Penny: You're extorting a date out of me?
Stuart: I kinda have to. The cousin who's getting married is the cousin I usually go to weddings with.

Leonard: Look at that. To my friend, Leonard, from Stan Lee, Excelsior!
Howard: Awesome. Mine says, "To my friend, Howard, from Stan Lee, Excelsior!"
Raj: Mine says, "To Raj, from Stan Lee."
Howard: That's 'cause you pissed him off about his character names.
Raj: Hey, I didn't even mention Dum Dum Dugan, or Green Goblin, Matt Murdock, Pepper Potts, Victor von Doom. Oh, and worst of all, Millie the Model.

Raj: Fantastic Four, Daredevil, Invincible Iron Man, Happy Hogan, Curt Connors.
Howard: Would you just let it go?
Raj: And worst of all, Fin Fang Foom.

Howard: Sheldon, why do you have all these unopened paychecks in your desk?
Sheldon: Because most of the things I'm planning to buy haven't been invented yet.
Howard: But there must be thousands of dollars here. Why don't you put it in the bank?
Sheldon: I don't trust banks. I believe that when the robots rise up, ATMs will lead the charge.

Raj: I can't wait to ask Stan Lee why he insists on giving all his characters first and last names that start with the same letter.
Leonard: Oh, come on, why would you do that?
Raj: Bruce Banner, Reed Richards, Sue Storm, Stephen Strange, Otto Octavius, Silver Surfer, Peter Parker. Oh, and worst of all, J. Jonah Jameson, Jr.

Penny: Okay, look, they sent me the ticket. I told them I wasn't driving and they were all, if it wasn't you, who was it?
Sheldon: So you betrayed me?
Penny: No, it wasn't a betrayal. It was more of a can't afford any more points on my license. I already have to buy my insurance from this place in the Cayman Islands.

Sheldon: I've decided that I'm going to have Mr. Lee sign my copy of this month's Batman.
Howard: That's crazy. Stan Lee had nothing to do with Batman.
Sheldon: Yes, which is why no one else will ask him to sign one, and I will be the possessor of a unique, albeit confusing, artefact, which will set me apart from the hoi polloi of comic book fandom
